[EM] Election Calculator additions: equal rankings IRV

[Brian Olson]

The Election Calculator now includes three different behaviors of IRV:
duplicate a vote across choices it ranks equally ( aka "whole" )
split a vote across choices it ranks equally
disqualify a vote so long as it has a tie for first place (it can come 
in in later rounds when through disqualification of choices it has a 
unique first).*

I hope this helps illustrate and discover the differences between they 
variations.



* I don't think this should not be done in practice. A real voting 
machine should reject invalid ballots and require the voter to try 
again. I included it for some sort of "completeness", and because my 
front end makes no enforcement against casting tied-ranking ballots.
